Can Rubicon Lockers Function as Limited Slip When Not Locked?

The short answer is no. Rubicon models do not feature a traditional LSD within their drivetrain system when their locker is inactive. The often misunderstood Brake Lock Differential (BLD) system, while innovative, cannot replicate the mechanical benefits of an LSD, as it relies on the vehicle’s braking system to manage wheel spin, rather than providing continuous, mechanical traction.

However, this doesn’t mean your Rubicon is left without tricks up its sleeve. The Traction Control System is there to aid in reducing wheel slip by intelligently applying brakes to the wheel that’s losing grip, therefore transferring power to the wheel with traction—an ingenious workaround that helps maintain forward momentum when the lockers are not engaged.

In conclusion, the Rubicon’s legendary off-road capabilities are a product of its well-engineered differential lockers. Though not an LSD by traditional standards, your Jeep is equipped with a foolproof system designed to tackle the rigors of off-road adventures with uncompromised mastery.
